Lindsay Rowntree — Chief Operating Officer at ExchangeWire

Lindsay Rowntree has been appointed as Chief Operating Officer at ExchangeWire, a prominent B2B media and events company focused on the global advertising technology industry. ExchangeWire is well known for its editorial coverage, research, and flagship events such as ATS (Advertising Trading Summit), which bring together senior leaders across programmatic advertising, data, and digital media. Rowntree has been a long-standing figure at ExchangeWire, previously serving as Head of Content and later in editorial leadership roles, giving her deep institutional knowledge of the company and the broader AdTech ecosystem. This promotion to COO represents a significant internal elevation, reflecting ExchangeWire's confidence in Rowntree's operational and strategic capabilities. In her new role, she is expected to oversee the day-to-day operations of the business, support the company's growth strategy, and help coordinate across its media, events, and research divisions. Her background in content and editorial positions her well to align operational priorities with ExchangeWire's core value proposition as a trusted industry voice. The appointment underscores a broader trend of media and intelligence companies in AdTech investing in experienced internal talent to drive organizational maturity. As ExchangeWire continues to expand its global footprint and diversify its product offerings, having a seasoned operator with editorial and industry expertise in the COO seat is a strategic asset.

This leadership change reinforces ExchangeWire's position as a serious institutional player in the AdTech media and intelligence space, rather than simply a trade publication. By elevating an internal leader with deep content and industry expertise to the COO role, ExchangeWire signals a maturing organizational structure capable of scaling its events, research, and media businesses more systematically. For the broader AdTech ecosystem, ExchangeWire's editorial and event platforms serve as important neutral ground for industry discourse, and strong operational leadership helps ensure the continuity and quality of that function. Competitors in the AdTech media and events space — such as Digiday, The Trade Desk Insights, and IAB Europe — will take note of this consolidation of leadership. The move also reflects a wider industry trend of promoting women into senior operational roles within AdTech-adjacent businesses, contributing to gradual improvements in leadership diversity across the sector.
